Doemens’ Pilot Brewery for Education and Research

Glass Bottle Filler

PET Filler

Pilot Malting

In 1895, Dr. Albert Doemens wrote in the register of the newly founded First Munich Brewing Academy: "An understanding should be ingrained in the students that practical knowledge, observation and a sharpening of the senses form the essential foundation for a successful career as a brewer." With this vision, Dr. Albert Doemens laid the groundwork for what Doemens has become, a leading light of the international brewing, beverage and food industries.

Milestones in Recent Decades

1965 Establishment of the Doemens School non-profit organization

1980 Commissioning of the 5 hl pilot brewery and packaging plant for education and research

1982 The first training program for Beverage Industry Process Manager

1989 The first training program for Food Industry Process Manager

1992 Federal accreditation as a technical academy

1993 The first training program for Beverage Industry Commercial Manager

2000 Founding of the World Brewing Academy in cooperation with the Siebel Institute of Chicago, USA

2003 Start of the Internet distance learning program (web-based training in Brewing Technology)

Since 1965, more than 2000 graduates have received an education from Doemens and are now employed in positions of responsibility in the brewing and beverage industry in more than 80 countries around the world.

Bottle Cleaning

The Doemens filling plant has a pilot bottle washer at its disposal with a capacity of 2,500 bottles per hour, which is available to clients for conducting studies on new detergents, labels, glues, bottles and additives. Trials can also be performed on PET bottles using the bottle washer. The team at Doemens applies their extensive knowledge and experience to offer clients support in the planning of and, if desired, the supervision of experiments.

Doemens’ Pilot Brewery for Education and Research

Doemens’ pilot brewery exists since 1980 and consists of a 4 unit brew work, a fermentation and storage with a bottling tank area as well as a combined layer filter for powder and sterile filtration.

The 5 hl brew work comprises of a mash tank, lautertun, mash copper and a whirlpool for the hot break removal. Any conceivable classic infusion mashing and decoction mashing is possible. The boiling works with heating surfaces in a tank jacket and at atmospheric pressure.

Technical details brew house

Grist load max. 120 kg

Cast wort quanity max. 6 hl

Masching schemes Infusion / decoction mashing

Lautering Lauter tun with 3 rakes

Wort boiling atmospheric, jacket heating surfaces

Hot break removal whirlpool (2 openings)

Wort cooling two stages with ice water

The fermentation and storage cellar area consist of open fermenters, standing cylindro-conic as well as flat fermenting and storage tanks. Thereby, any common fermentation, maturation and storage processes may be simulated. Storage at temperatures below 0 °C is possible.

The students attending the English language brewing courses use the pilot brewery to produce their Meistersude (beer brewed as part of their final exam). The students work together in groups to independently develop their own beers, from wort production through to monitoring and directing fermentation and maturation. In addition, brewing experiments involving adjuncts are also integrated into the coursework.

However, the pilot brewery is also available for conducting research projects and developing new products. The following represent a mere sampling of the projects successfully carried out on the pilot brewery at Doemens in support of its teaching and technical staff: recipe design and process development for launching new beers (with subsequent scale up to production level), the production of trial batches of beer using new raw materials and combinations of ingredients, the development and optimization of production processes (yeast management, fermentation process, etc.) and the creation of fermented, non-alcoholic beverages, among others.

Glass Bottle Filler

The pilot filler for glass bottles at the Doemens filling plant can be reserved for volumes up to 15 hl. Should a client wish to bottle a trial batch for market studies or simply a small consignment – whatever the case may be – the team at Doemens is always eager to present their clients with the wide range of options available and to demonstrate optimal techniques and methods for bottling their products. Of course, the filler is also available for product development and testing, for example for cleaning trials or to test concepts for novel beverages.

PET Filler

PET is an indispensable part of packaging non-alcoholic beverages. The difficulty in performing filling trials with PET bottles for product launches or for research has been solved by Doemens. Clients now have the opportunity to conduct filling trials using a small number of PET bottles. As long as the client can provide blow-molded PET bottles, Doemens can fill and label bottles with very low oxygen uptake under scale-up conditions on its PET filler.

Pilot Malting

The pilot malting plant facilitates the production of our own malt with a pouring of up to 200 kg of grain. Soaking, germination and kilning take place in one unit; the turning of the germination material is done according to the Lausmann principle.

This pilot malting plant with its capacity adjusted to the needs of the pilot brewery, the malting of new barley and wheat varieties as well as alternative grain varieties and following brewing tests in a 5 hl scale are possible.
